The Cost Of Photovoltaic Power Generation In China Has Fallen By 90% In 10 Years.

New energy department, deputy director of the national energy administration chuang-jun li 12 situation of photovoltaic industry development in our country is in Beijing, as the policy support and technical progress, the photovoltaic industry to grow rapidly, cost reduction and product update speed accelerating, from 2007 to 2007, photovoltaic KWH cost decreased by about 90%, photovoltaic power generation is expected to achieve parity in three or four years to get to the Internet.

Li said that the current social environment for photovoltaic development has changed dramatically compared with the relatively cold and clear 10 years ago. In 2005, there were only 5 megawatts of new photovoltaic power generation installed in China, accounting for 0.36 percent of the global total. In 2005, the total photovoltaic capacity of the country was 70 mw, which was only 1.35% of the global total. In 2017, the total installed capacity of the country will reach 53G, accounting for 39% of the total power supply installed in the country, and the first in the world for five consecutive years, accounting for half of the global increment. In 2017, the total installed capacity of photovoltaic power generation in China reaches 130 gw, the world's largest total installed capacity in three consecutive years, accounting for 32.4 percent of the global total. By the end of 2017, photovoltaic power generation about 256.5 billion KWH, BiaoMei saving more than 80 million tons, the total emissions of carbon dioxide, sulfur dioxide, nitrogen oxides, respectively for 210 million tons, 680000 tons and 210 million tons.

Li emphasized that in 2017, photovoltaic power generation also realized the quality, double lift and the amount of discarded light and the double reduction of the light rejection rate. Continuous optimization of power generation form, and continuous increase of distributed photovoltaic installation; The power generation layout is continuously optimized, and the newly added installed power is transferred to the Middle East. The product structure is continuously optimized, and the proportion of efficient components is obviously improved. He introduced, advances in technology have made photovoltaic power generation cost at an unexpected speed decrease: in 2017, domestic polycrystalline silicon slice, cell and component prices fell by 26.1%, 25.7% and 33.3% respectively, photovoltaic power generation costs have fallen to about 7 yuan per watt, component cost has dropped to 3 yuan/watt.
